In the On-Location Lighting workshop I teach our students that one of the 7 reasons to use flash is to express your vision. As photographers, light is the notes we use to compose a song. If you only know half the notes the song you create will be pretty limited in tone and originality. If you however know the full range of notes you can create a masterpiece! If we are able to recognize and make use of natural light as well as incorporate artificial light where needed we can truly express our vision and create our own masterpieces!
